Application filed August 16, 1913. Serial No. 785,040.

To all whom it may concern Be it known that I, Fnnonniox Econ, a citizen of the United States, residing in the city of Bridgeport, county of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Embroidery- Machines; and 1 do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprises certain new and useful improvements in embroidery machines, and has particular relation to special attachments for holding the needle device of embroidery machines The primary aim of the invention is to improve the needle device of an embroidery machine so that the same can be readily at tached to or detached from a needle bar, and to so connect the needle carrier that the same can be retracted or projected to render the needle operative or inoperative, means being provided for automatically locking the carrier in either position.

In carrying out the objects of the invention generally stated above, it will be understood, of course, that the same may be embodied in various forms, one simple and practical embodiment thereof being shown in the accompanying drawings, where1n Figure 1 is a top plan view of a needle bar equipped with the improved needle device. Fig. 2 is a sectional view thereof taken on the line 22, Fig. 1. Fig. 3 is a sectional view taken on the line 33, Fig. 1. Fig. l is a sectional view taken on the line M, Fig. 2. Fig. 5 is a detail perspective view of the needle carrier.

The improved needle holding attachment for embroidery machines comprises in its general organization a support having a flat base plate 1 in one longitudinal edge of which notches 2 are formed for the reception of bolts 3 to rigidly but removably fasten the base plate in position transversely across the needle bar 5. The base plate 1 carries an upstanding flange 6 at its longitudinal edge opposite the notches, and the upper longitudinal edge of the said flange has a notch 7 at its forward end; an intermediate notch 8, and to the rear of and adjacent the notch 8, a shallow notch 9, the notches forming pivot seats, to be referred to. The forward end of the flange 6 projects beyond the forward end of the base plate 1 and has a depending portion that terminates in a flat laterally projecting needle clamp seat 10 that is parallel with but in a lower plane than base plate 1. Flange 6, adjacent the forward notch '7, is provided with a latching opening 11.

Links 12 have their lower ends pivotally attached to studs 13 carried by the flange 6, the studs 13 being disposed, respectively, forward of notch 8 and to the rear of notch 9. The upper ends of the links 12 are pivotally connected to studs 1& carried, respectively, by the forward and rear portions of the needle carrier 15. The needle carrier 15 has a depending forward end from which a flange 16 projects laterally, the flange 16 being provided with a groove 17 and cooperating with a plate 18 and a bolt 19 to form a needle clamp. At the center of its top portion, the carrier 15 is provided with an upstanding flat extension 20 provided with an opening 21. A latch plate 22 has its intermediate portion bolted to extension 20, the upper portion of said plate being offset and carrying a stud 23 that is adapted to pass through opening 21. A spring 24 is coiled about stud 23 and normally holds the offset portion of plate 22 away from extension 20. The lower end of plate 22 is bifurcated, as indicated at 25 and straddles and engages a groove formed in a latching bolt 26 that normally projects through an opening 27 formed in the carrier.

The latching bolt 26 engages the latching opening 11 of flange 6 when the carrier is in its forward position, as shown in Fig. 1 to lock the carrier in its forward position, and when the carrier is in its rear position, as shown in Fig. 8, binds against the flange 6 with suflicient force to normally retain the carrier in its rear position. The notches 7, 8, and 9, form seats for the reception of the pivot studs 14 of the carrier 15 when said carrier is in either position, one example thereof being shown in Fig. 2. And the flange 10 at the forward end of flange 6 provides a seat for the needle clamp, when said clamp is in its forward position.

It will be seen from the foregoing that by means of the link connection of the carrier 15 with the flange 6, the needle clamp is always retained in position to hold the needle 28 in a horizontal plane, and that when the needle is retracted, as shown in .jected relative to Fig. 3, the needle lies in such a position that its point is shielded by the flange 6.

In Fig. 1 the relative positions of the needles when in their retracted and projected positions are shown, the two upper needles being shown in projected or operative position, while the lower needle is shown retracted or in an inoperative posi tion.

In operation, the extension and plate 22 are grasped by the fingers, the pressure on plate 22 releases the latching bolt 26 from engagement with the opening 11, or from engagement with the flange 6, according to the position in which the carrier is in, whereupon said carrier may be readily swung forwardly or rearwardly on its hinge connections, such swinging movements being facilitated by using the extension and plate as finger grips.

The invention as described is particularly useful in shifting needles, but of course it will be understood that the same could be used in connection with piercers, as the operations of the same are practically alike. And in this connection, it should be noted that all operations of shifting the needle or carrier are performed from behind the needle so that the operator does not have to reach in front of the point thereof with the ever present danger of injury from said point.

WVhat-I claim as my invention is 1. A device of the character described comprising a base support, means for rigidly attaching the support to a needle bar, a carrier, links connecting the carrier to the support to permit the carrier to be elevated and retracted or projected relative to the support, and means for locking the carrier in either its retracted or projected position.

2. A device of the character described comprising a base, means for detachably fastening the same to a needle or piercer bar of an embroidery machine, a carrier having link connections with the base to permit the carrier to be elevated and retracted or prothe base, and locking means carried by the carrier and adapted to engage the base to retain the carrier either projected or retracted.

3. A device of the character described comprising a base support, a carrier, means connecting the carrier to the support and permitting the carrier to be elevated and retracted or projected relative to the base support, aclamp carried by the carrier, and a combined finger-grip locking means carried by the carrier for retracting and projecting the carrier and for engaging the support to retain the carrier in projected or retracted positions.

4. A device of the character described comprising a base support having a depressed forward seat,'means for rigidly atby the taching the support to a needle bar, a carrier having a clamp adapted to engage the seat when the carrier is projected, means connecting the carrier and support and permitting the carrier to'be elevated and'longitudinally projected or retracted relative to the support, and means for locking the carrier in either -a retracted or projected position.
